Phyllis Wan


I am a PhD student in the Department of Statistics at Columbia University. I am supervised by Prof. Richard A. Davis.

My research interest lies in the study of complex data structures, such as networks and time series. I am especially interested in scenarios where heavy-tailed observations are present and where novel statistical tools are called for!

Before coming to Columbia, I obtained my bachelor degree in mathematics from the University of Hong Kong.
